the user who created the invitation has the same E-Mail address as another user. As soon as the E-Mail Addresses are made unique, the accept-link works.

So this calendar breaking issue persists for 5 years and nobody tried to fix it yet?

if you read the related ticket would know it's not simply something that can be fixed. The linked tickets contain possible solutions but they all come with drawbacks.

The easiest "solution" is to not allow duplicate email addresses, which, if you're an admin, you can make this a policy. Use LDAP or another user backend and provision your accounts from there.

hinformatik commented 3 months ago

The ammount of nonsene in this issue is buffeling.

  1. There should be a warning in nextcloud that states that calendar invites will not work if you try to create a user with a duplicate email.
  2. The error message that appears if you try to accept an invite should be more helpful.
  3. Why not disallow creating duplicate mail accounts completely and solve this issue that way?

I opened this issue to make it very easy and clear what the problem (and the workaround) is. It is, however, still a bug, whether you want to fix it or not.

Closing this issue is fine for me, I solved it for myself and I wanted to make a clean and clear ticket for others to find and possibly somebody to fix. I hope someday it will be solved for others as well.

Hello tom-ch1! I would like to know the workaround that you are following to solve this. Thank you in advance!
